If you've been known to enjoy a box of wine, here's how to transform a freshly emptied box into a huge ice pack for a large cooler. Take the bag that used to hold the wine, rinse it out, and fill it with water. Lay it flat in the freezer, and wait. You have a huge, reusable ice pack for a cooler of any size.

Ice packs aren't hard to come by, but they're usually on the small side, and you need several to cool a cooler unless you want to just open a bag of ice in it. If you're also known to enjoy a box of wine now and again, this useful tip (from the folks at America's Test Kitchen) gives you a way to reuse those plastic bags that the wine comes in instead of just tossing them out with the box.

It's pretty straightforward (we would add that you should probably rinse the bag out first), but the video above shows you how it's done. Remember, boxed wine goes bad faster than bottled, so keep it chilled or drink it up. At least now you have something to do with the box when you're done.
